HANIh-WHEIEL.

To all whom it may concern:

Be it'known that 'I, 'HENRY J. WIEGAND', a citizen of the United States,residing at Milwaukee, in the. county of Milwaukee and Stateof'Wisconsin, have invented new and useful. Improvements in HandVVheels, of

. which the following is a full, clear, concise,

and exact description, reference being had to the accompanying drawing,forming "a part of this specification. v

My invention relates to improvements in "hand wheels, and has for itsobject to im-.

prove the construction of the hand wheel. disclosed in my former Patent,'No. 821,272,

dated May22, 1906'. I

.One feature of my present invention resides in the construction of arim which is Figure 1 is a bottom plan view of the wheel." Fig. 2 is asectional-view taken'on line 2-2, Fig. 1, and Figs. 3 and 4 are detailviews.

The'hand wheel illustrated is formed entirely of sheet metal, with theexception of the hub. The rim' is preferably formed in two parts, anupper member 1 and alower member 2. The members land 2 comprise stampedcircular plates or rings so 'bent transversely as to form a rimsubstantially circul'arin cross-section when the same arefitted togetheras illustrated. In practice I' prefer to make the upper member of widermaterial than the lower member, so that when the same is .benttransversely, as illustrated, the curve of its cross-section is greaterthan a semi-circle. This renders the rim'of greater strength than byforming the two members alike. Furthermore, by forming the upper memberas described,

" the edges of both members are hidden when the rim is viewed from thetop. Owing to the fact that the two members are curved Patented Mar. 7,1916.

. Application filed October s, 1908. Serial No. 456,802.

substantially concentrically, they may be placed together, edge to edge,on the outside to form a substantially smooth and continuous surfacewithout the necessityof any special preparation of their edges. Inpractlce I prefer to have the inner edge of the upper member overlap theinner edge of the lower member, inasmuch as the ap pearance ofthe wheelis not marred thereby, and this arra'ngementpermits the parts to be moreeasily assembled. The two members are held together in the. manner here-The rim is mounted on inafter described. a spider, which preferablycomprises three arms 3 radiating from a substantially cir{ cularcentral-portion 4. The arms Bare preferably formed integrally withtheportion 4, the entire spider being stamped from sheet-metal. For thepurpose of strengthening the arms and giving the same th appearance ofbeing solid, the same are curved .transverselv, their edges-beinghiddenwhen the wheel is viewed from the top. The ex tremities of the.arms 3 are flat and are secured to the inside of the upper "member ofthe rim, .preferably'by means of rivets 5. The lower member of the rimhas notches stamped therein to permit the insertion of the ends of thearms 3 in the upper member of the rim and' 'to form tongues 6. Thetongues 6 are'bent downwardly to engage the under side of the arms 3 andare secured thereto, preferably by solder. It will thus be seen thatthe-two. members of the rim are held togetherlby securing both of thesame to; the arms 3. The central portion 4 of the spider is secured byrivets 7 to the annular flange 8"of ahub 9. The hub is preferably formedof cast-metal and provided with a socket or recess 10 for the re-'ception of a shaft. A screw 11 threaded into the side of the hubprovides means whereby the same may be locked to the shaft.

In order tostrengthen the spider and relieve the strain on the rivets 7when the wheel .is in use, I" provide the central portion 4 withdownwardly extending flanges 12, adapted to fit tightly around theflange 8 on the hub. The provision of the flanges l2 adds greatly to thestrength of-the wheel. Projecting outwardly from" one of the flanges 12is 'a -pointer- 13, referably stamped integrally therewith. i

It will thus be seen that a hand-wheel constructed in accordance with myinvention, has-the appearance and all of the advantages of a solidwheel, while the l same may be; produced at a much smaller cost.

Of course, my inventionds not limited to the specific constructionillustrated, and various modifications maybe made therein -without dearting from the spirit thereof. I

l Having t us described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. A hand wheel comprising a spider havingradial arms and a hand rimsecured to the extremities of said arms and-having a gripping spacebetweeneach adjacent pair of said arms, said-rim comprising a pluralityof transversely curved metallic rings rigidly secured to the armsof saidspider to form a ring substantially circular in cross section.

2. In a hand wheel, the combination with a spider having radial arms, ofa hand rim formed of transversely curved sheet metal rings rigidlysecured to the arms of said spider to form a ring substantially circularin cross section, the ends'otsaidarms being concealed within said rim. r

3. In a handwheel, the'combination with a spider having radial arms,of ahand rim formed of a pair-of transversely curved sheet metal ringsrigidly secured to the arms of said spider to form a ring substantiallycir cular in cross section, the outer edges of said rings being flushand the inner edges thereof being overlapped. I

4. In a hand heel, the combination with, Y

a spider having radial arms, of a hollow hand rim-substantially circularin cross-sec-' tion and formed of a pair of sheet-metal rings, the inneredges of said rings overlapping, andthe outer edges thereof being flush,one of said rin'gs having apertures for. re ceiving the .ends or. saidarms and having tongues secured to said arms, said arms being secured tormgs.-

. 1 6., In a hand wheel, the combination with a sheet-metal ,spiderhaving radial arms c'urved transversely, of'a hollow hand rimsubstantially circular in cross-section and formed of a pair ofsheet-metal rings, said rim having apertures formed therein forreceiving the ends of said arms.

7. In a hand wheel, the combination with a sheet-metal spider havingradialarms curved'transversely, of a hollow hand rim substantiallycircular in cross-section and formed of a pair of sheet-metal rings, one

of said rings having apertures formed there- 1n for receiving. the endsof said arms and having tongues formed thereon and secured to said arms,the other of said rings being riveted to saidarms.

8. A hand wheel having a spiderformed of sheet metal andprovided witharms radiating from the central portion thereof and a hub secured to thecentral portion of said spider, said central portion having its edgesbetween said arms bent to form flanges to engage the sides of said hub.i

9. A hand wheel having a spider formed of sheet metal and provided witharms radiating from the central portion thereof, said arms being curvedtransversely and said central portion having its edges bent to formangularly disposed flanges continuous with said arms, and a hub securedto the central portion of said spider between the flanges thereof.

In witness whereof, I have hereunto subscribed my name in the presenceof two witnesses.
